Abstract
A liquid level measuring device comprises an inner-tube unit having an inner tube and at least one inner-tube coil surrounding the inner tube; an outer-tube unit having a plurality of outer tubes, each outer tube having a plurality of outer-tube coils disposed thereon, the outer tubes being stacked, the inner tube being arranged inside the outer tubes and being risen and fallen as a level of a liquid in the outer tubes varies; and a control unit electrically connecting to the respective outer-tube coils, the control unit transmitting a set of position coded signals to the outer-tube coils disposed on an individual outer tube, the control unit determining the liquid level according to an induced signal generated by the inner-tube coil. Said device has many advantages including low cost and modular design, and such a device is easily to be deployed.
